Reference of 52449-98-6, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 52449-98-6, Name is Oxolane-2-carbonyl chloride, molecular formula is C5H7ClO2. In a Patent，once mentioned of 52449-98-6
The invention provides low viscosity iodinated aryl compounds, useful as X-ray contrast agents of formula I wherein n is 0 or 1, and where n is 1 each C6R5 moiety may be the same or different; X denotes a bond or a group providing a 1 to 7 atom chain linking two C6R5 moieties or, where n is 0, X denotes a group R; each group R is a hydrogen atom, an iodine atom or a hydrophilic moiety M or M1, two or three non-adjacent R groups in each C6R5 moiety being iodine and at least one R group in each C6R5 moiety being an M or M1 moiety; each M which may be the same or different, is a non-ionic hydrophilic moiety; and each M1 independently represents a ?CHOHCON(R1)2 group wherein each R1, which may be the same or different, is a hydrogen atom, an OH group or a C1-6 alkoxy or optionally hydroxylated C1-5 alkyl group; at least one R group in the molecule being an M1 moiety; and isomers thereof.
